High oil pressure reading on a 2005 nissan aramada reads high when i turn it on and while driving but once completely stopped it goes back to normal, checked oil level and looks fine

You may have a defective oil pressure sending unit on the engine or the oil pump relief spring may be sticking. Have the oil pressure tested with a special tool that goes in the oil port the sender is screwed into to determine the cause of the high pressure.;
